Dr Trigoni's interests lie in localization, communication and coordination protocols for networked sensor nodes. Her research has been applied to a number of scenarios, from people and animal tracking, to road traffic monitoring, controlling autonomous vehicles and sensing industrial processes. Details of her research activities are available at the Sensor Networks Group's website.



Dr. Niki Trigoni is a University Lecturer at the Oxford University Department of Computer Science and a fellow of Kellogg College. She obtained her PhD at the University of Cambridge (2001), became a postdoctoral researcher at Cornell University (2002-2004), and a Lecturer at Birkbeck College (2004-2007). Since she moved to Oxford in 2007, she established the Sensor Networks Group, and has conducted research in communication, localization and in-network processing algorithms for sensor networks. Her recent and ongoing projects span a wide variety of sensor networks applications, including indoor/underground localization, wildlife sensing, road traffic monitoring, autonomous (aerial and ground) vehicles, and sensor networks for industrial processes. She has co-authored more than 60 peer-reviewed conference and journal papers, including publications at Sensys, IPSN, Infocom, Mobihoc and ACM Transactions on Sensor Networks. In 2012, she edited (with Prof. Krishnamachari) a themed issue of the Philosophical Transactions of the Royal Society A, which is a compilation of landmark papers from leading researchers in her field. She has also edited the Proceedings of the Third International Conference on GeoSensor Networks (2009). She served as the Tracking Session Chair at ACM Sensys 2012, Chair of the 3rd Intl. Conf. in GeoSensor Networks in 2009, and as co-Chair of the Workshop on Environmental Sensor Networks in 2007. She has reviewed a large number of papers for conferences and journals in the area of sensor networks, and grant proposals for EPSRC, NERC, NSF, Singapore Ministry of Education and the British Council.
